Movie S5. Quantitative dynamics of stripe formation and refinement. The mean spot fluorescence, instantaneous fraction of active nuclei, and accumulated amount of mRNA produced as a function of AP position are shown for different time points as in Fig. 3. The time stamp indicates time since the beginning of nc14. The mRNA produced us shown in the case of infinite half-life (mRNA accumulation) and of a half-life of 7 min. All data are obtained by averaging four different embryos. Error bars are SEM.
